Control Mode Selection Strategy Design Over Full Temperature Range For Laser Gyro
Aiming at the problem that the laser gyro frequency stabilization device is easily disturbed by temperature chan-ging,in order to ensure the laser frequency stabilization effect of gyro over full temperature range,this paper designed a control mode selection strategy.According to different modal characteristics in the gyro sweeping mode process,by comparing the magni-tude of the backscattering characteristic voltage in each mode,suitable gyro and its control modes were screened out at room tem-perature,and then through the temperature cycle experiment,the suitable modes were further selected and fixed for the frequency stabilization control at the full temperature to ensure the full temperature precision of the gyro.Finally,the experimental results show that the optimal mode obtained under the screening strategy is used to realize the stable operation of the laser gyro at full temperature,which meets the practical requirements.
